BACKGROUND Technical Field

The disclosure relates to transmission schemes of radio signals inwireless communication systems, and in particular to a method and adevice for multi-antenna transmission.

Related Art

Massive Multi-Input Multi-Output (MIMO) becomes a research hotspot ofnext-generation mobile communications. In the massive MIMO, multipleantennas experience beamforming to form a relatively narrow beam whichpoints to a particular direction to improve the quality ofcommunication. A base station and a User Equipment (UE) can performanalog beamforming at a Radio Frequency (RF) end to realize a narrowbeam with a low RF link cost.

In 3rd Generation Partner Project (3GPP) New Radio discussions, there issome company proposing that, in downlink transmission, a base stationneeds to indicate to a UE in advance a beam used for receiving a ChannelState Information Reference Signal (CSI-RS) and a beam used for datatransmission respectively, so that the UE performs receptions usingcorresponding analog beams.

SUMMARY

The inventor finds through researches that the scheme in which beamsused for CSI-RS and data transmission are indicated respectively maycause the following: beam indicators corresponding to CSI-RS receptionand data reception are not aligned, while the CSI-RS and the data arefrequency-domain multiplexed on a same multicarrier symbol; thus, the UEcannot determine which beam indicator is used for receiving thecorresponding multicarrier symbol.

In view of the above problems, the disclosure provides a solution.

Embodiment 3

Embodiment 3 illustrates a diagram of an embodiment of a radio protocolarchitecture of a user plane and a control plane according to thedisclosure, as shown in FIG. 3. FIG. 3 is a diagram of an embodiment ofa radio protocol architecture of a user plane and a control plane. InFIG. 3, the radio protocol architecture of a UE and a base station (gNBor eNB) is represented by three layers, which are a Layer 1, a Layer 2and a Layer 3 respectively. The Layer 1 (L1 layer) is the lowest layerand implements various PHY (physical layer) signal processing functions.The L1 layer will be referred to herein as the PHY 301. The Layer 2 (L2layer) 305 is above the PHY 301, and is responsible for the link betweenthe UE and the gNB over the PHY 301. In the user plane, the L2 layer 305includes a Medium Access Control (MAC) sublayer 302, a Radio LinkControl (RLC) sublayer 303, and a Packet Data Convergence Protocol(PDCP) sublayer 304, which are terminated at the gNB on the networkside. Although not shown, the UE may include several higher layers abovethe L2 layer 305, including a network layer (i.e. IP layer) terminatedat the P-GW on the network side and an application layer terminated atthe other end (i.e. a peer UE, a server, etc.) of the connection. ThePDCP sublayer 304 provides multiplexing between different radio bearersand logical channels. The PDCP sublayer 304 also provides headercompression for higher-layer packets so as to reduce radio transmissionoverheads. The PDCP sublayer 304 provides security by encrypting packetsand provides support for UE handover between gNBs. The RLC sublayer 303provides segmentation and reassembling of higher-layer packets,retransmission of lost packets, and reordering of lost packets to as tocompensate for out-of-order reception due to HARQ. The MAC sublayer 302provides multiplexing between logical channels and transport channels.The MAC sublayer 302 is also responsible for allocating various radioresources (i.e., resource blocks) in one cell among UEs. The MACsublayer 302 is also in charge of HARQ operations. In the control plane,the radio protocol architecture of the UE and the gNB is almost the sameas the radio protocol architecture in the user plane on the PHY 301 andthe L2 layer 305, with the exception that there is no header compressionfunction for the control plane. The control plane also includes a RadioResource Control (RRC) sublayer 306 in the layer 3 (L3).

A base station for wireless communication,comprising: a first transmitter, to transmit first information andsecond information; and a second transmitter, to transmit a first radiosignal in a first time interval; wherein the first information and thesecond information are used for determining a first parameter and asecond parameter respectively, the first parameter and the secondparameter are used for multi-antenna related receptions respectively;the second parameter is used for a reception of a second radio signal;if a time-domain resource occupied by the second radio signal comprisesthe first time interval, the second parameter is used for a reception ofthe first radio signal, otherwise, the first parameter is used for areception of the first radio signal; the first parameter and the secondparameter are parameters indicating spatial QCL with a first referencesignal and indicating spatial QCL with a second reference signalrespectively.
 14. The base station according to claim 13, wherein thefirst radio signal is a reference signal and the second radio signalcomprises data; the first information is carried by a higher layersignaling, and the second information is carried by a higher layersignaling.
 15. The base station according to claim 13, wherein thesecond transmitter transmits a downlink signaling; wherein the downlinksignaling is used for determining that the first radio signal is areference signal and the second radio signal comprises data.
 16. Thebase station according to claim 13, wherein the second transmittertransmits the second radio signal; wherein a time-domain resourceoccupied by the second radio signal comprises the first time interval.
